Art masterpieces seized by the Nazis and thought to have been destroyed in British bombing raids on Germany during WW2 have been found behind rotting food in a loner’s modest apartment near Munich, Germany’s Focus Magazine reported Sunday.

The collection, which includes works by Picasso, Renoir, Matisse and Marc Chagall, among many others, has an estimated worth of $1.6 billion.

The artworks, confiscated and deemed ‘degenerate’ by the Nazis, who showed them at an exhibit in 1937, were put in the care of Hildebrandt Gurlitt, who, as a well known art dealer in Germany at the time, was tasked with selling them off for cash by Joseph Goebbels.

Gurlitt, however, seems to have kept many for his own personal collection, despite having reported the artworks destroyed during the bombing of Dresden.
